WATER-HE ATER.

To all whom it may concern:

Be it known that I, ERNEST A. PETERSON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in VVater-Heaters and theLike, of which the following is a description.

My invention belongs to that class of devices known as heaters andparticularly to that class known as circulating water heaters, and hasfor its objects the roduction of a sim le, cheap and efficient ieater ofthe kind escribed.

To this end my invention consists in the novel construction,arrangement, and combination of parts herein shown and described andmore particularly pointed out in the claims.

In the drawings wherein like reference characters indicate like orcorresponding parts; Figure 1 is a vertical-partial sectional View of mypreferred form of heater. Fig. 2 is a vertical partial sectional view ofa slightly modified form; and Fig. 3 is a crosssectional view of theform shown in Fig. 1 taken substantially on line 33 of Fig. 1.

Referring to the drawings, the preferred construction comprises an innershell 1 and an outer shell 2, spaced therefrom, provided with heads 3and 4 forming a heating chamber surrounded by a water jacket. The head 3is preferably extended as at 5 forming an inlet, and the head 4similarly extended as at 7 to form an outlet. The inlet and outlet pipes6 and 8 are shown.

plurality of water tubes 9 are provided and each arranged with its endsconnecting the water jacket or chamber between the shells 1 and 2 withthe body part extended into the heating chamber. As is shown the tubes 9are preferably bent or twisted so that they substantially act as bafflesand impede the passage of the heated gases through the heating chamber.The inner and outer shells 1 and 2 and the tubes 9 are preferably madeof very thin material, the tubes being secured in position in anypreferred or suitable way. The heads 3 and 4 may be secured on theshells 1 and 2 in any preferred or suitable manner.

Preferably in the lower end of the heating chamber is arranged somesuitable form of burner as a gas burner similar to that shown. Theburner shown comprises the body part 11 arranged to receive theilluminant from the supply pipe 12, 13 being a plate arrangedSpecification of Letters Patent.

in 1.1 with a space or opening 14 as shown. The late 13 may also beprovided with a plura ity of apertures 15 therein,and a wire gauze 16arranged below the plate to prevent back firing. The burner is supportedat the lower end of the heating chamber with an air opening 17 as shown,in any suitable or preferred manner brackets 18 being shown for thepurpose.

In the modified form shown in Fig. 2, a partition 22 is provided in thewater jacket preferably in the upper part dividing the same into twoparts. In this form the inlet is preferably arranged in the upper partof the water jacket near the artition so that the incoming fluid enterstl i e inlet from the pipe 6 and flows down and into the tubes 9 asindicated by the arrows, thence upwardly into the upper water acket andthrough the outlet into pipe 8. As is shown the partition 22 ispreferably arranged with a space 23 so that the water in the lowerjacket is not in contact with the partition touching the hot water inthe upper water jacket, that is, there are substantially two partitions.

The usual form of storage tank may be used in combination with my device(not shown) if the same is desired, the heater creating a circulationthrough the storage tank whether water is being drawn from the storagetank or not, or whether the water is under pressure. It is obvious thatin the form shown in Fig. 1 the water will circulate within the heater,without using a storage tank, that is, the parts may be so proportionedthat a considerable quantity of water is stored within the heater itselfcirculating therein when the heat is applied.

As shown a baffle plate 19 or its equiva lent with suitable aperturestherein may be placed in the upper part of the heating chamber tofurther impede the passage of the heat therethrough, and a flue pipe 21arranged on the heater to conduct away the excess of heat and wasteproducts of combustion.

Having thus described my invention, it is obvious that variousimmaterial modifications may be made in the form, construction, anddesign shown without departing from the spirit of my invention; hence Ido not wish to be understood as limiting myself to the exact form,construction, or design shown.

What I claim as new, and desire to secure by Letters Patent is:

1. A device of the kind described, comprising a heating chamber providedwith a water jacket, a transverse partition dividing the water jacketinto two parts with an inlet in one part and an outlet in the other, incombination with a plurality of water tubes, each tube having one endconnected with one chamber in the water jacket and the other end withthe other chamber with the gody part extended into the heating cham 2. Adevice of the kind described, comprising a heating chamber provided witha water jacket therefor, a transverse partition arranged in the upperpart of said water jacket dividing the same into a plurality of partswith an inlet in one part and an outlet in the other, in combinationwith a plurality of water tubes each having one end connected to thelower chamber and the upper end connected to the up er chamber of saidwater jacket with the ody part extended into the heating chamber.
